At the October 1975 meeting of the Eastern Section of the Association it was not a burdensome task to summarize the results of a symposium on reefs and evaporites. The occasion for the summary coincided with the annual cocktail party and banquet and my contribution consisted of somewhat frivolous comments embellished by broad and sweeping gestures. On these pages, however, constrained by the requirements of formal publication, a summary paper that pretends to provide readers with organization and structure can not evade a responsibility for identifying opposing issues. Worse, the summarizer can not adopt a completely neutral stance and thus escape the displeasure of colleagues with whom he is in fundamental disagreement. Thus, I accept full blame if the paragraphs that follow seem less than evenhanded and appear to tilt away from a strict adherence to balance and equity.

Reefs and Evaporites—Concepts and Depositional Models
With the Michigan basin having long been recognized as a classic area for the study of evaporite deposits, most of the papers included in this volume were presented at a 1975 meeting focusing on the Michigan basin. Topics covered include: Depositional environments of pinnacle reefs in the northern shelf of the Michigan basin; Sedimentology and depositional environments of basin-center evaporites; depositional environment in southeastern Michagan; An evaporitic lithofacies continuum; and Reefs and evaporites—a summary.
